Hello,
This may look 'not nice' solution, but in my working place I
parsed
A Csv USING xslt... and then producted an XML out of what was contained
in it..
If that Is an option for you, I can help out...
Regards
marco

I don't have a lot of free time on my hands, but I would be interested
in helping out in this effort. I'm probably not as big a java whiz as
some of the people on this project, but I'd love the chance to help out,
learn some more, and contribute to the community.

Yep, this sort of pattern is quite popular and very flexible.
Obviously xml is a prime example: an event-based parser emits events to
a listener. If the user wants a complete in-memory representation, then
they plug in a listener that generates a DOM tree (or whatever they
want).
The ASM java bytecode manipulation lib is similar. A java .class file
reader emits events. If the user wants an in-memory representation of
the class structure, they attach the appropriate listener to build one.
It's much more flexible than an API that *always* loads everything into
memory, and stores it in a datastructure that it has decided, not the
user.
I'm not volunteering to work on a csv parsing project..but I would
second this suggestion. It's only an extra couple of classes, and makes
the result much more flexible.
Regards,
Simon
